| Abstract | State-of-the-art advances---in particular, anticipated advances generated by LSI---have given fresh impetus to research in the area of parallel processing. The motives for parallel processing include the following: 1. Real-time urgency. Parallel processing can increase the speed of computation beyond the limit imposed by technological limitations. 2. Reduction of turnaround time of high priority jobs. 3. Reduction of memory and time requirements for "housekeeping" chores. The simultaneous but properly interlocked operations of reading inputs into memory and error checking and editing can reduce the need for large intermediate storages or costly transfers between members in a storage hierarchy. 4. An increase in simultaneous service to many users. In the field of the computer utility, for example, periods of peak demand are difficult to predict. The availability of spare processors enables an installation to minimize the effects of these peak periods. In addition, in the event of a system failure, faster computational speeds permit service to be provided to more users before the failure occurs. 5. Improved performance in a uniprocessor multi-programmed environment. Even in a uniprocessor environment, parallel processable segments of high priority jobs can be overlapped so that when one segment is waiting for I/O, the processor can be computing its companion segment. Thus an overall speed up in execution is achieved. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
